ERROR: Command error (PrepareAssertionError): Cannot read properties of undefined (reading 'toLowerCase')

Issue description

ERROR: Command error (PrepareAssertionError): Cannot read properties of undefined (reading 'toLowerCase')

Steps to reproduce the problem

1. I am using the ODNWeather library (https://github.com/CosmiCloud/ODNWeather)
2. In the ODNWeather log, there is an error "error publishing to the network. Error: Get publish failed. Reason: undefined."

According to a website, the (reading 'toLowerCase') error is due to: The "Cannot read Property 'toLowerCase' of null" error occurs when the toLowerCase() method is called on a variable that stores a null value. To solve the error, make sure to only call the toLowerCase method on strings.

Specifications

• Ubuntu 20.04 (LTS) x64

Error logs (node logs)

journalctl -u otnode --output cat -fn 100
